A hospital pharmacist presents an article at a journal club. She reports that the average weight of the subjects in the study is 172 pounds, with a standard deviation of 10.

Choose the correct statement:

1. Most of the subjects had a weight within 5 pounds of the mean.
2. Most of the subjects had a weight within 10 pounds of the mean.
3. Most of the subjects weigh between 172-182 pounds.
4. Most of the subjects weigh between 162-172 pounds.
5. The mode of these data is 162 pounds.

Answer :

Final answer:

Most of the subjects weigh between 162-172 pounds.

Explanation:

The correct statement is: Most of the subjects weigh between 162-172 pounds.

To determine this, we need to consider the range within one standard deviation of the mean. In this case, one standard deviation is 10 pounds, so most of the subjects would fall within the range of 162-182 pounds, which includes the mean of 172 pounds.

Therefore, option 4) Most of the subjects weigh between 162-172 pounds is the correct statement.
